Application illed December 4, 1924. Serial No. V753,904.l

My invention relates to protective covers, and more articularly to aprotective cover 'for bath tu s.

Formerly, before built-in bath vtubs were used, it was customary to putin the bath vide a protective covering for the tubs after the majorityof the other work in the bath roomhadbeen completed. Since built-in bathtubs have come into use, however, it has become necessary to install they bath tub before the partitions-are in place orthe plasteri'ng -ortile-setting is done in the bath room, as the-bath tub is inset into thewall adjacent thereto. It has been found that when a bath tub isinstalled before this work is done, it is very frequently damaged bythedropping of tools into the same. or other hea objects, or by the shoesof persons standlng therein when working ond the walls orv otherportions of the bath room adjacent thereto. It has accordingly beenfound very desirable to provide some means y of protecting the bath tubafter it has been installed, to prevent damage thereto.

.It is the purpose of my invention to prourposes referred to above,comprising a portion that is adapted to coverthe entire bath tubincluding the rim thereof, and to provide means for securing the same inposition so that the covering cannot be easily removed. The covering ispreferably of Cai such stren h that if a mechanic desires to stand ont esame to work above the bath tub. the covering will support his weightwithout damage thereto. A

It is a further urpose of the invention to provide means or holding theprotective covering member in position on a bath tub that will securelyhold the covering in position, anddo so without damaging-the tub.

As bath tubs vary somewhat in size, it is desirable to provide.adjustable means engaging the inner face of the tub to preventtransverse movement of the covering relative to the tub', and to furtherprovide means 'for holding the coverinfrom upward movement relatlve tothe tu xdflhe covering preferably rests on the top e ho ding the samefrom movement 'upwardly relative to the tub referably, comprisesclamping means engaging the tub and means detachably engageable withsaid. clamping vtiling or other walll covering that is at 4body portionof the tub, and the means for means mounted on the protective coveringmember. vThe said means preferably comprises clamping members havingupward extensions provided with openings that are adapted to receivebolt-like members that are mounted for axial movement into and out ofengagement with the openings in the clamping members.

The'clamping means engaging with the inner face of the tub preferablycomprises eccentrically-mounted, curved members that are made of amaterial that will not injure the enamel on the inner face of the bathtub. Vhen the work in the .bath room is completed, ythecover member,with the bolt-like members and the eccentrically-mounted clamping means,is removed, while the Vclamps remain in position on the edge of the tub,these being so proportioned and vso mounted that the same are imbeddedin the plastering or mounted in the back of, the

r0- vided adjacent the edge of the tub, an accordingly are hidden fromview. New

clamping members must be used for this purpose for each tub that isprovided with the protective covering.

fit these bath tubs,an extension member is provided that is detachablyengageable with the main body portion of the protective covering, andwhich may be of such a size as to properly tit the covering. to a tub ofanyhlengtn that it is desired to cover there- Wit Other objects andadvantages'of the inj so Some bat-h tubs are longer than others, and .inorder to provide for a covering that will vention will appear as thedescription of the accompanying drawings proceeds.: However, I desire tohave it distinctly understood that I do lnot intend to limit myself n tothe exact details shown orvdescribed,but that I intend tof include aspart of my invention all such obvious. changes and modifications ofparts as would occur t/o a person skilled in this art and asy would fallwithin the scope of the claims.

Fig. 10 is a vertical, sectional view there-` of; and i Fig. 11 is adiagrammatic horizontal, sectional view of a bath room showing a bathtub positioned in the corner thereof,` and the arrangement of securindevices for the protective covering for suc an installation.

Referrin provided 'with a laterally extending flange portion 11 aroundthe top ed e thereof, said ange portion being imbedde y in theplastering 12 providedon the walls 13-when the installation iscompleted. In using my prot tective covering, the bath tub 10 isinstalled before the plastering has been applied to the walls, and theprotective covering`14 is putv in place thereon. The protectivecovering,

' as will be clear from Fig. 1,v does not extend is ordinarily exposeshort, laterally extending flanges 17 that are adapted to rest on theupper surface of the edge portion of the tub 10 or on the latern allyextending flanges 11 thereof. Said clamping members are further provided.with a lower laterally extending flange portion 18 that isscrew-threaded to receive the in detail to the drawings, in- Figs. 1 an2 is shown a bath tub 10`that is screw-threaded clampin member 19 thatis adapted to be adjusted' y turning the same in the member 18 to clampthe flange 17 tightly against the top edgeof thetub 10 on the flangeportions l11 thereof. The

clamping members 16 are lfurther provided provide means vfor removingthe bolt-like members 22 from the openings 21, the same are providedwith notches 26 providing shoulders 27 with which a tool such as achisel may-be engaged to move the bolt-like l members 22 to the right inFig. 3, out ofen- 90 gagement with the members 20.

The covering member 14 is preferably made of a material made up of aplurality of plies 28 of Wood, which are covered on the opposite facesthereof with plies 29 of metal. The metallic plies 29 are preferablybent around the corners or edges of the plies 28, as indicated at 30, toprotect the edges o'f the plies 28 with the metallic covering, saidbent-over portions 30 being held in position in any lde sired'manner.

A plurality of adjustable holding members are providedl for holding thecover member 14 from shifting transversely of the bath tub, said membersbeing indicated by the numeral 31 and being preferably curved botheccentrically to the pivot member 32 and to conform tothe curvature 33of the tub 10 between the body portion thereof and the flange portion11,- thus providing a compound curved rtion 34 on the member 31 engagingwitllmthecurved portion 33 vof the tub. The pivot member 32 ispreferably made in the form of a bolt-like member, and it will be seenthat when the bolt like member 32' is turned so as to loosen the members31 that the same can be turned freely to any desired position to adjustthe same so that the curved faces 34 thereof will be in snug engagementwith the curved faces 33 of the tub 10 on opposite sides thereof. rlhenthe members 32 can be drawn up, tightening the members 31 and holdingthe same against turning on their pivots. Thus the covering 14 is heldfirmly from transverse movement relative to the tub 10, and asthemembers 31 are preferably made of wood or similar material that can besmoothly finished so as to cause no damage .to the finish o'f-the'innerface of the bath tub, it will be seen that the clamping means,

` ,while holding the covering member from' 'movement .transversely ofthetub, will .in no wa vdamage thetub.. r the'arrangement shown in Figs.,l and 2, it will ,-bevseen that the bracket members 23 and boltlikemembers 22 are mounted on along those edges of the coverl4 adjacentthewalls 13 It will be clear from opposite ends ofthe tu'b. When a'bathtub 1s p vacedin a corner, as shown i'n Fig. 11, an does not extend fromone wallto another, the covering member 14 is preferably rounded offat'the end thereof to conform to the rounded end of the tn b the'holding means 31fbeing located as in the previously described form, butthe bolt-like members l22 and the brackets 23 are preferably7 locatedthat lie Figa-1 to 3, inclusive, that due to the 'shortness of the ange17 and the thinness of the member 20, the plastering 12 or other .-Wellcovering material will extend over the j rim'or flange portion 11 of thetub to such anextent as to completely cover the exposed portions of theclamping members 16, which .can,..accordingly be leftin position withoutv anynobjection thereto.

Fig. 7 the 'protective cover member 14 is sho'wn as being provided witha different form of securing means for holding the same from -movementaway from' .the tub 10, said means comprising a rod member 35 having ahook end 36 a apted to engage under the cross bar 37 provided in thedrain 38 of the tub, said member 35 being provided. A with athreaded endadapted to screw- .threadedly receive the nut :3Q-and a washer 37 being-placed between said `nut 36 tand Instead of using' the clamping membershown in Fig 7 the cover member v14 may be. rovided with a hook rod 39having a hoo -shaped end 40 that enters the overflow drain opening 4 1in the tub 10, and which is provided with a nut 42 to screw-threadedlyengage therewith, and with a washer 43 bearing against the cover 14.

While the'cover membed described above will lit theordinarystandard-'size bat-h tubs,

some bath tubs are made of .greater len hr than the' standard size, andin order t -it the cover member to such tubs the extension shown inFigs. 9 and 10 is preferably proi ,l vided. Said extension eomprises'abody porsame thickness as said cover member.

tion 44 that is made preferably of the same material as the cover member14 and ofS the aid extension 44 is preferably provided with a -pair offlanges 45 which are preferably in the form of metallic strips bolted orotherwise secured by the securing members 46 to the edge portion of themember 44 adjoining the end edge ofthe member 14 to which said member 44is to be a plied. The edge portion 47 ofthe member 14 preferably fitssnugly between the flanges 45, and the exing members 16 comprisin abracket member 48 corresponding in al respects to the bracket member 23,and-a bolt-like 'mem-I ber 29 corresponding in all respects to thebolt-like member 22, and operattension 44 preferably provided `withmeans l jthat is adapted to co-operate with `the clamping in thesame waylto hold thecover 'i j member from movement upward relatively to thebath tub. It will be evident that the extension 44, due to the provisionof the flanges 45, will not be capable 'of vertical `movement relativeto the member 14, and
